2.1i: Floorpanner: Floorplanner does not remove 'constrained' blocks when 'area constraints' is used

Description

Keywords: floorplanner, replace, placement, area, constraint

Urgency: Standard

General Description:When the option 'Floorplan' -> 'Assign Area Constraint' is done after'Floorplan' -> 'Replace All with Placement' the original 'Replace All withPlacement' constraint remains as well as the assigned 'Area Constraint'.

Solution

Before doing an 'Area Constraint', highlight the desired hierarchy in the 'DesignHierarchy' window. Select 'Floorplan' -> 'Remove'. This will remove the'Placement Constraint' on the selected hierarchy. Now do 'Floorplan' -> 'AssignArea Constraint' on the highlighted hierarchy. The hierarchy will now have theproper constraint on it.
